Enum Fetched 

pub enum Fetched {
    Present(Value),
    Absent,
    Unknown(Unknown),
}

What one round trip established.

Variants

Present(Value)

The repository holds records there. Always an array, each element {"uri": …, "value": …} — one element for a reference naming one record, one per record for a reference naming a collection. One shape means a caller reads both the same way, and the uri is what a refusal carries so a person can open the record it came from.

Absent

The repository answered, and holds nothing there: no record at that key, or no record in that collection.

Unknown(Unknown)

Neither was established; see Unknown.

Trait Implementations

impl Clone for Fetched

fn clone(&self) -> Fetched

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Fetched

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Fetched

fn eq(&self, other: &Fetched) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
